摘要
目的研究三维灰阶超声在甲状腺结节诊断中的应用。方法对56例62个甲状腺结节在二维超声的基础上进行三维检查,并与手术、病理结果对照分析。结果三维灰阶超声能迅速提供肿物的三维重建冠状断面图像及与周围组织的关系。三维超声中良性实质结节有完整的高回声界面,88．9％有宽窄均匀的暗环;而69．2％恶性实质结节无完整的高回声界面,恶性实质结节表现为76．9％内部无暗环或暗环宽窄不一。4个结节向腺体外生长并侵犯颈动脉提示恶性肿物。甲状腺囊实性肿物以良性为多,占92．6%,三维超声中恶性囊实性结节表现为实质部分表面不规则,凹凸不平。结论甲状腺三维超声成像拓宽了超声检查的视野,提供直视的、立体的肿块形态学特点,为甲状腺疾病的一种新的成像方法。
Objective To apply two-dimensional and three-dimensional （3D） uhrasonography in the diagnosis of thyroid nodules clinically. Methods Two-dimensional and 3D uhrasonography were performed in 56 patients with 62 thyroid nodules. The results were compared with those of operation and pathology, Results Images of 3D uhrasonography provided relationship between nodules and adjacent tissue rapidly. Benign solid nodules of thyroid showed a complete hyperechogenic interface,and 88,9% nodules showed regular halo; whereas 69.2% malignant nodules showed no complete hyperechogenic interface,and 76.9% malignancy without halo or with irregular halo. There were nodules extending to carotid presented to be malignancy. Solid cystic nodules in thyroid were benign mostly （92.6%）, and malignant mixed echogenic nodules presented irregular surface, Conclusion Three-dimensional uhrasonography extends the view of two-dimensional ultrasonography and provides direct stereo morphologic features and is a new imaging modality for thyroid diseases.
